Running traces on a local machine
|
|||
|
|
=================================
|
|||
|
|
|
|||
|
|
Prerequisites
|
|||
|
|
-------------
|
|||
|
|
- Install `Apitrace <https://apitrace.github.io/>`_
|
|||
|
|
- Install `Renderdoc <https://renderdoc.org/>`_ (only needed for some traces)
|
|||
|
|
- Download and compile `Piglit <https://gitlab.freedesktop.org/mesa/piglit>`_ and install his `dependencies <https://gitlab.freedesktop.org/mesa/piglit#2-setup>`_
|
|||
|
|
- Download traces you want to replay from `traces-db <https://gitlab.freedesktop.org/gfx-ci/tracie/traces-db/>`_
|
|||
|
|
|
|||
|
|
Running single trace
|
|||
|
|
--------------------
|
|||
|
|
A simple run to see the output of the trace can be done with
|
|||
|
|
|
|||
|
|
.. code-block:: console
|
|||
|
|
|
|||
|
|
apitrace replay -w name_of_trace.trace
|
|||
|
|
|
|||
|
|
For more information, look into the `Apitrace documentation <https://github.com/apitrace/apitrace/blob/master/docs/USAGE.markdown>`_.
|
|||
|
|
|
|||
|
|
For comparing checksums use:
|
|||
|
|
|
|||
|
|
.. code-block:: console
|
|||
|
|
|
|||
|
|
cd piglit/replayer
|
|||
|
|
export PIGLIT_SOURCE_DIR="../"
|
|||
|
|
./replayer.py compare trace -d test path/name_of_trace.trace 0 # replace with expected checksum
|
|||
|
|
|
|||
|
|
|
|||
|
|
Simulating CI trace job
|
|||
|
|
-----------------------
|
|||
|
|
|
|||
|
|
Sometimes it's useful to be able to test traces on your local machine instead of the Mesa CI runner. To simulate the CI environment as closely as possible.
|
|||
|
|
|
|||
|
|
Download the YAML file from your driver's `ci/` directory and then change the path in the YAML file from local proxy or MinIO to the local directory (url-like format ``file://``)
|
|||
|
|
|
|||
|
|
.. code-block:: console
|
|||
|
|
|
|||
|
|
# The PIGLIT_REPLAY_DEVICE_NAME has to match name in the YAML file.
|
|||
|
|
export PIGLIT_REPLAY_DEVICE_NAME='your_device_name'
|
|||
|
|
export PIGLIT_REPLAY_DESCRIPTION_FILE='path_to_mesa_traces_file.yml'
|
|||
|
|
./piglit run -l verbose --timeout 300 -j10 replay ~/results/
|
|||
|
|
|
|||
|
|
|
|||
|
|
Note: For replaying traces, you may need to allow higher GL and GLSL versions. You can achieve that by setting ``MESA_GLSL_VERSION_OVERRIDE`` and ``MESA_GL_VERSION_OVERRIDE``.
